1. The TriDye DNA Ladder was not designed for precise quantification of DNA mass but can be used for approximating the mass of DNA in comparably intense samples of similar size.
2. We recommend loading 5-10 μl (0.5-1.0 μg) of TriDye DNA ladder per gel lane.
3. In general, it is recommended to load 1ul per mm of gel lane.
4. TriDye DNA Ladder is stable for at least 6 months at 25°C.
5. For long term storage, store at 4°C or -20°C. If stored at -20°C, mix well after thawing.

• DNA Markers & Ladders Selection Tool

1. Why are the DNA ladders showing up on my Southern blot? What is the sequence or composition of the ladder bands?
2. How can I quantify the amount of DNA in each band of a marker?
3. Can I use Midori Green with the DNA Ladders from NEB?
4. Can I use SYBR^® and/or GelRed^® dyes with the DNA Ladders from NEB?
5. Why is my DNA Ladder floating out the wells and Why are there no bands visible in my DNA ladder gel lane?
6. What are the differences in the four versions of 2-Log, 100 bp and 1 kb DNA Ladders that NEB sells?
